Oil Painting Outside the Window

She had been paralyzed in bed for thirty years, and the only scenery she could see was the sycamore tree outside the window. She watered the tree every day, and even though she couldn't reach it, she asked her son to help. The tree grew and covered half of the window. Her son wanted to cut it down, but she refused, saying: "It looks at the outside world for me." Later, she became seriously ill and said before she fell into coma: "Open the curtains." When her son opened the curtains, he found that the sycamore tree was covered with notes, which made a rustling sound when the wind blew. Each note has the same sentence written on it: "Mom, I saw today..." From the first day she was paralyzed, her son wrote one and hung it up every day for thirty years, more than 10,000 pieces. She never said she wanted to look outside, but he knew.
